"System, redeem [Bloodline Upgrade Scroll] and use it to upgrade [Uchiha Bloodline Limit]!"
"Ding Dong! [Uchiha Bloodline Limit] is raised to the first level, and the Host activates the Sharingan."
"Ding Dong! [Uchiha Bloodline Limit] is upgraded to Level 2, and the Host activates the Sharingan."
"Ding Dong! [Uchiha Bloodline Limit] is upgraded to Level 3, and the Host activates the Three Tomoe Sharingan."
"Ding Dong! [Uchiha Bloodline Limit] is upgraded to Level 4, and the Host activates the Mangekyō Sharingan."
Naruto exchanged four [Bloodline Upgrade Scrolls] in one go, immediately upgrading his Sharingan to the [Mangekyō Sharingan] level.
However, when he tried to further upgrade the [Uchiha Bloodline Limit] to obtain the Eternal Mangekyō, a system prompt sounded:
"Ding Dong! [Uchiha Bloodline Limit] has been upgraded to the highest level. If the Host wants to obtain [Eternal Mangekyō], please exchange and use a [Blood Synthesis Scroll] after preparing another pair of Mangekyō Sharingan."
Naruto pondered the system's prompts and realized that achieving his dream of obtaining the Eternal Mangekyō in one go was currently impossible.
At the moment, there were only three pairs of Mangekyō Sharingan in the entire Ninja World. If Sasuke's Mangekyō from the future was included, it would make four pairs.
(Madara's eyes could be considered Rinnegan, and even if Naruto took them, it would only be a pair of Rinnegan.)
"Which of these four pairs should I choose? Which one can I get?"
After some thought, Naruto abandoned the idea for now, as none of the current holders—Obito, Itachi, or even Danzo—were opponents he could face.
"Let's see what abilities my current Mangekyō Sharingan has."
Mangekyō Sharingan is known as the "Eye of the Soul's Depiction," with each Mangekyō possessing unique abilities, representing the deepest desires of the soul.
Naruto used the Swift Movement Technique [Shunshin no Jutsu] to arrive at a quiet riverbank, gazing into the water to see his reflection and what his Mangekyō might look like.
But what caught his eye first was a 12-year-old boy with yellow hair, a face that was barely handsome, and three whisker-like lines on each side of his mouth.
"This is me... Uzumaki Naruto. But am I really Naruto?"
The reflection in the water slowly began to blur.
In that moment, Naruto realized that although he was Uzumaki Naruto in this world, he was not the same Naruto he used to be.
He remembered his old world—a world without ninjas, but full of modern technology like televisions, mobile phones, airplanes, and missiles.
His parents, friends, and classmates all seemed like distant memories.
"Who am I? Am I still myself?"
In this world, his parents were dead, and only a few people truly cared for him—Iruka and Hinata. However, even Iruka had his own life, and Hinata was too young for him to share his secrets with.
"I am alone... but can I change my destiny?"
Naruto turned his thoughts to his abilities, using his Mangekyō Sharingan to test its power. As he focused on his left eye, it transformed into a black eight-pointed star, surrounded by a blood-red hue. A strange sense of mystery filled the air.
When he injected chakra into his left eye, the world around him seemed to slow down. The flow of the river, the fish swimming, all seemed to move in slow motion. His hand rose, but it felt as though it was moving much faster than before.
"Time has accelerated! No, wait—my time has accelerated!"
Naruto realized that it wasn't the world that had slowed down, but his own body and reactions had become faster. This was the power of his left-eye Mangekyō: [Time Acceleration]. His body speed, reaction speed, and even hand seal speed had all been enhanced. His physical strength had grown immensely, and his ninjutsu release was faster, making him even more formidable.
However, he realized the only downside was the risk of vision loss and potential longevity issues from overusing the Mangekyō Sharingan.
"If the left-eye Mangekyō is Time Acceleration, then what about the right-eye Mangekyō?"
Curious, Naruto closed his left eye and focused chakra into his right eye. The same black eight-pointed star appeared, spinning rapidly.
Without a second thought, he took a kunai and slashed his left arm, causing the skin and muscles to tear, blood pouring out.
But in the next moment, the blood reversed, and the wound healed as if it had never happened.
"As I thought!"
Naruto smiled, excitement filling his heart. This was the power of his right-eye Mangekyō: [Time Reversal]. It allowed him to reverse injuries, healing any wound that wasn't instantly fatal or didn't affect his soul.
Naruto realized that with the combination of his left-eye [Time Acceleration] and right-eye [Time Reversal], he had obtained a truly powerful and nearly immortal body.
"Could it be that my soul's deepest desire is for power?"
Naruto pondered this, but then an even more exciting realization hit him.
"Time Reversal... It can let me open the Eight Gates infinitely!"
"What's going to happen next?"
"Infinite Eight Gates?"
Naruto's grin grew wide as the possibilities seemed endless. His path forward was clear, and the world had suddenly become much more exciting.
